Freq Resp Low Freq Adjustment

In this adjustment, flatness corrections are turned off and amplitude error versus frequency is measured from 9 kHz to 3 GHz (Option F03), or 7.5 GHz (Options F07, F13, and F26) for Preamp Off, and from 100 kHz to 3 GHz (Option P03), or 7.5 GHz (Options P07, P13, and P26) for Preamp On. The data is then normalized to 50 MHz to generate corrections relative to 50 MHz. Flatness corrections are generated for each attenuator step for both preamp off and on. The data is then stored in the analyzer memory.

  1. Refer to the main equipment list for a list of alternative models (if available).
  2. The 3.5 mm (m) to 3.5 mm (m) adapter between the power splitter and the DUT is critical in this adjustment. Proper connector care and torqueing practices must be followed in order to insure optimal performance.
